It would be half of the coefficient of x squared added to both sides:
So half of 8 ( the coefficient of 8x) is 4;
The number 4 squared is 16, so you would add that to both sides.
You do this so that you can easily factor the left side: x^2 + 8x + 16 = 4 + 16
(x + 4)(x+4) = 20
Answer:
Step-by-step explanation:
22/7x4^2=50.28
3x3=9
50.28-9=41.28
Answer:
C
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
114° is an external angle of the triangle , thus
y + y = 114°
2y = 114° ( divide both sides by 2 )
y = 57° → C
Answer:
P-value = 0.00028
Step-by-step explanation:
The statician performs an hypothesis test for the mean difference.
As the alternative hypothesis is<em> Ha: μd ≠ 0</em>, we know that it is a two-tailed test.
The test statistic is t=6.163.
For a two-tailed test and 8 degrees of freedom, this corresponds to a P-value of:
This P-value is smaller enough to reject the null hypothesis at almost any significance level.
